                                                What makes a house a home?

     Not size, of course. I've been in some of the grandest houses in America, and it's readily apparent no

one lives there. Earlier this year, I had dinner in a mud hut in Ethiopia, where we sat on chairs next to the

hostess' bed -a home that had more warmth than any house I've been in since.

     Now John Edwards is exploring what makes a house a home in his just-released Home: The

Blueprints of Our Lives. There Edwards writes, " This is a book about homes, the values they rest on,

the dreams they are filled with, and the people they have shaped. The houses and circumstances are

different, but much of what you find inside will be familiar."      

     Whether you're sitting in an airport right now, waiting to fly to your childhood home for Thanksgiving,

or in your own home waiting for the relatives to arrive, you know what he's talking about.

     We've lived in our townhouse for 21 years. The loose windows that make noise in the wind. The

fireplace so shallow it holds only one log. The kitchen window that offers a view of the world passing by.

It's where friends sit on the kitchen counter drinking wine while dinner is being fixed.I lived there for only

18, but it will always be my true home. Even the lamp in the west living room window, which I could see

far down the road when driving home late at night, still shines.

     While all this talk about childhood memories can be warm and comforting, home is whom you're with,

not where you are. As Edwards writes, "Home is family. Home is safety. Home is faith."

Happy homecoming.
